  • Minimization of Copper Losses in Copper Smelting

    21/09/2012· All samples were held at temperature for 30 min and then immediately quenched in water to obtain relatively uniform slag, matte, and copper microstructures to allow microprobe analysis to be carried out. From experience, this holding time was found sufficient for all phases to reach thermodynamic equilibrium, while minimizing any MgO contamination of the slag by the MgO crucible

    Blast Furnace Slag is a by-product from the manufacturing of steel in a blast furnace. Initially in its molten form, it is diverted to a granulator where it is quenched with water and rapidly cooled to form glassy, non-metallic granules which are silicates and aluminosilicates of calcium. These granules are dried to produce Granulated Blast Furnace Slag (GBFS) and then ground to a suitable

  • Blast Furnace Slag - Material Description - User

    If the molten slag is cooled and solidified with water and air quenched in a spinning drum, pellets, rather than a solid mass, can be produced. By controlling the process, the pellets can be made more crystalline, which is beneficial for aggregate use, or more vitrified (glassy), which is more desirable in cementitious applications. More rapid quenching results in greater vitrification and

  • Ground Granulated Blast Furnace Slag (GGBS) |

    This slag is periodically tapped off as a molten liquid and then rapidly quenched with large volumes of water. This process optimizes the cementitious properties and produces granules like coarse sand. This granulated slag is then dried and ground to a fine powder. It is also knows as slag cement because it has similar properties as cement clinker.

    To obtain a good slag reactivity or hydraulicity, the slag melt needs to be rapidly cooled or quenched below 800 °C in order to prevent the crystallization of merwinite and melilite. To cool and fragment the slag a granulation process can be applied in which molten slag is subjected to jet streams of water or air under pressure. Alternatively, in the pelletization process the liquid slag is

    Slag cement generally improves workability, finishability and pumpability of plastic concrete. It may provide a small decrease in water demand (see SCIC #5). Slag cement will tend to increase time of initial set, which is often a benefit in warm weather. In cooler weather, accelerators, heated materials or lowering the percentage of slag cement in a mixture (as a portion of cementitious

  • Mechanism of Alkali-Activated Copper-Nickel Slag

    A large number of studies have shown that copper-nickel slag generally contains SiO 2, CaO, Fe 2 O 3, and Al 2 O 3, and many of them exist in the form of a glass phase. These products exhibit hydraulic potential and pozzolanic activity [9, 11–14]. Chen et al. examined the preparation of mine filling materials by using water-quenched nickel slag. The results indicated that the water-quenched

  • Differential heat treatment - Wikipedia

    Differential heat treatment (also called selective heat treatment or local heat treatment) is a technique used during heat treating to harden or soften certain areas of a steel object, creating a difference in hardness between these areas. There are many techniques for creating a difference in properties, but most can be defined as either differential hardening or differential tempering.
